Description
Die Erfindung betrifft eine Winkelmesseinrichtung gemäß dem Patentanspruch 1.The The invention relates to an angle measuring device according to the claim 1.
Winkelmesseinrichtungen, häufig auch Drehgeber genannt, dienen zur Messung von Drehbewegungen eines drehbar gelagerten Körpers, insbesondere einer Welle, über eine oder mehrere Umdrehungen (Multiturn-Funktionsweise). Die Drehbewegung wird dabei inkremental oder absolut erfasst. In Verbindung mit Zahnstangen und Zahnrädern oder mit Gewindespindeln lassen sich mit einer Winkelmesseinrichtung auch lineare Bewegungen messen.Angular displacement measuring instruments, often also called rotary encoder, are used to measure rotational movements of a rotatably mounted body, in particular a wave, about one or more turns (multi-turn mode). The rotational movement is recorded incrementally or absolutely. In conjunction with racks and gears or with threaded spindles can be with an angle measuring device also measure linear movements.
Über Anschlusskabel werden der Winkelmesseinrichtung eine Betriebsspannung zugeführt und die Messsignale abgenommen und an eine Folgeelektronik weitergeleitet. Hierzu ist bei bekannten Winkelmesseinrichtungen an einer Kappe der Winkelmesseinrichtung eine Öffnung vorgesehen, durch die hindurch das Anschlusskabel der Winkelmesseinrichtung zugeführt und dort mit einer geeigneten elektrischen Anschlusseinheit kontaktiert werden kann.Via connection cable be supplied to the angle measuring device an operating voltage and the measurement signals removed and forwarded to a subsequent electronics. For this purpose, in known angle measuring devices on a cap the angle measuring device an opening provided through which the connection cable of the angle measuring device supplied and contacted there with a suitable electrical connection unit can be.
Der Erfindung liegt die Aufgabe zugrunde, eine Winkelmesseinrichtung der eingangs genannten Art zu schaffen, die mit einfachen Mitteln eine zuverlässige und schnelle Montage ermöglicht, wobei die Winkelmesseinrichtung gegenüber der Umgebung gut abgedichtet werden kann und eine elektrische Kupplung an der Winkelmesseinrichtung zuverlässig arbeitet.Of the Invention is based on the object, an angle measuring device of the type mentioned above, with simple means a reliable one and fast assembly, the angle measuring device being well sealed from the environment can be and an electrical coupling to the angle measuring device works reliably.
Diese Aufgabe wird erfindungsgemäß durch die Schaffung einer Winkelmesseinrichtung mit den Merkmalen des Patentanspruchs 1 gelöst.These The object is achieved by the Creation of an angle measuring device with the features of the claim 1 solved.
Demnach ist zur Optimierung der Leichtgängigkeit und Funktion einer elektrischen Kupplung sowie zur Verbesserung der Dichtheit der Winkelmesseinrichtung zumindest ein Abstandshalter vorgesehen, mit dessen Hilfe die Kappe relativ zur Leiterplatte derart positioniert ist, dass die Öffnung bezüglich des elektrischen Kupplungselements ausgerichtet ist. Durch diese exakte relative räumliche Zuordnung der Kappe gegenüber der Leiterplatte kann ein hoher Grad an Dichtheit im Bereich der elektrischen Kupplung reproduzierbar erreicht werden.Therefore is to optimize the smooth running and function of an electrical coupling and for improvement the tightness of the angle measuring device at least one spacer provided, with the help of the cap relative to the circuit board is positioned such that the opening with respect to the electrical coupling element is aligned. Due to this exact relative spatial allocation of the cap across from The circuit board can have a high degree of tightness in the area of electrical coupling can be achieved reproducibly.
Ferner weist die Winkelmesseinrichtung Mittel auf durch die letztlich eine bezüglich der Winkellage eindeutige Zuordnung zwischen der Kappe und eines elektrischen Kupplungselements sichergestellt ist. Das vorgenannte Mittel ist beispielsweise eine formschlüssige Verbindung zwischen einem Grundkörper der Winkelmesseinrichtung und der Kappe Alternativ dazu können auch Passstifte direkt an der Kappe angebracht sein (oder Bestandteil der Kappe sein), die mit entsprechenden Bohrungen in der Leiterplatte eine winkeltreue Montage bedingen. Hier weist also die Kappe Elemente auf, welche mit der Leiterplatte derart zusammenwirken, dass eine relative Winkellage zwischen Kappe und der Leiterplatte durch einen Formschluss festlegbar ist.Further has the angle measuring means on by the ultimately one in terms of the angular position unique assignment between the cap and a electrical coupling element is ensured. The aforementioned Means is for example a positive connection between a body The angle measuring device and the cap Alternatively, too Dowel pins are attached directly to the cap (or component the cap), with corresponding holes in the circuit board require an angle-faithful assembly. So here the cap has elements on, which cooperate with the circuit board such that a relative angular position between the cap and the printed circuit board by a Form fit can be specified.
Häufig sind derartige Winkelmesseinrichtung Bestandteil eines Datennetzwerkes, z.B. mit einer Ethernet-Architektur, an das sie Messdaten liefern aber auch von diesem Daten empfangen. Deshalb werden in diesem Zusammenhang als elektrische Kupplungselemente oft bekannte Netzwerkstecker bzw. Netzwerkbuchsen verwendet, beispielsweise so genannte RJ45-Stecker bzw. entsprechende Buchsen.Frequently Such angle measuring device part of a data network, e.g. with an Ethernet architecture, to which they provide measurement data but also received from this data. Therefore, in this context often known as electrical coupling elements network connector or Network sockets used, for example, so-called RJ45 connector or corresponding sockets.
Gemäß einem weiteren Aspekt der Erfindung umfasst die Winkelmesseinrichtung zumindest ein zusätzliches Kontaktelement zur Herstellung einer elektrischen Verbindung mit einer oder mehreren Signalleitungen. Das Kontaktelement ist derart ausgestaltet, dass die Winkelmesseinrichtung als Ganzes in zumindest zwei unterschiedlichen Einbaulagen funktionsgleich anbaubar ist. Zu diesem Zweck können die entsprechenden Kontaktelemente als Ringkontakte ausgeführt sein. Gemäß einer vorteilhaften Variante können weiterhin die Kontaktelemente als Blechteile ausgestaltet sein. Alternativ dazu können die Kontaktelemente auch durch Leiterbahnen oder Pads auf einer Leiterplatte, die sich im Endbereich der Winkelmesseinrichtung befindet, definiert werden.According to one Another aspect of the invention comprises the angle measuring device at least one additional Contact element for making an electrical connection with one or more signal lines. The contact element is such designed that the angle measuring device as a whole in at least two different installation positions can be attached functionally identical. For this purpose can the corresponding contact elements be designed as ring contacts. According to one advantageous variant can Furthermore, the contact elements be designed as sheet metal parts. Alternatively, you can the contact elements also by conductor tracks or pads on one Printed circuit board, which is located in the end area of the angle measuring device, To be defined.
Mit Vorteil ist das Ende der externen Signalleitung, welches mit dem Kontaktelement zusammenwirkt als federndes Bauteil ausgestaltet, um eine zuverlässige elektrische Kontaktierung zu ermöglichen.With Advantage is the end of the external signal line, which with the Contact element cooperates designed as a resilient component, a reliable one allow electrical contact.
